The drawing shows the manner of con- 

 struction. The main standards or supports 

 are joined together by four cross-pieces or 

 rails fastened in place with dowels or long 

 wood screws. If screws are used procure 

 round-headed ones. The braces are fitted 

 in on the prop)er angles and fastened with 

 screws. The two upper and longest cross- 

 pieces are fastened to the edges of the stan- 

 dards to make a space between for the 

 sliding standards.
